Example: Using room variables

Control4 room variables provide greater flexibility in programming, letting you program using events and actions at the room level. 

Note: Most of the functions in Room Variables are available by selecting the Room object which is the recommended method for programming the room. Whenever possible, use the Room object rather than Room Variables.

To use room variables:

  1. Start Composer Pro and connect to a Director.
  1. Click Programming. In this view listed under every room in the project tree is a Room Variables object.
  2. Click to expand the Room Variables options. Room variables are available as events and actions.

    3. The room variables are described in the following table:

    Events/Actions

    Description

    CURRENT_SELECTED_DEVICE

    Lets you do programming when any device changes in the room.

    CURRENT_MEDIA

    Lets you do programming when any media changes in the room.

    POWER_STATE

    Lets you do programming when any device’s power state changes from True to False in the room (read only). A device in the room is required to detect the power state.

    CURRENT_VOLUME

    Lets you do programming when the volume of the currently selected audio path changes in the room (requires discrete volume). Use conditional programming.

    HAS DISCRETE_VOLUME

    Lets you do programming when any devices changes in the room (requires discrete volume). Use command programming.

    HAS_DISCRETE_MUTE

    Lets you do programming when Mute state is known (MUTE_ON or MUTE_OFF).

    IS_MUTED

    Lets you do programming when in Mute state (MUTE_ON).

    IN_NAVIGATION

    Lets you do programming when On-screen is available.

    USE_DEFAULT_VOLUMES

    Lets you do programming any time a selection changes to reset the default volume. For example, when changing from viewing a DVD to listening to music, the volume is reset to the default discrete set volume.

    DEFAULT_AUDIO_VOLUME

    Lets you program the default Audio volume.

    DEFAULT_VIDEO_VOLUME

    Lets you program the default Video Audio volume.

    VOLUME_IS_LINKED

    Lets you set programming not to affect already linked volume.

    MUTE_IS_LINKED

    Lets you set programming not to affect already linked mute state.

    ROOMOFF_IS_LINKED

    Lets you set programming not to affect already linked room off state.

    SELECTIONS_LINKED

    Lets you set programming not to affect already linked selections.

    ROOM_HIDDEN

    Lets you set programming to hide rooms from appearing on the navigation device.

    MEDIA_SCENE_ACTIVE

    Lets you set programming to set a media scene as active.
